How do I choose the right Telegizmos cover for my 8" SCT on a wedge?
While a standard fork-mounted 8" SCT fits the TG08 cover, a fork-mounted 8" SCT on a wedge requires the TG12. Measure your scope and mount set-up and compare it with the stated cover sizes before ordering.
Is the Telegizmos Standard Cover waterproof enough for my fork-mounted 11" SCT?
Yes, the material is waterproof, so the cover protects your scope from rain and dew during temporary outdoor storage. The TG11, listed for 10" and 11" SCTs, has a 64" circumference and 42" height; compare these with your set-up. For continuous outdoor exposure longer than 1 to 2 weeks, use a 365 Series cover.
What is the difference between the Standard Telegizmos cover and the 365 Series?
The primary difference is the intended duration of outdoor use.
-
Standard Cover: Designed for temporary outside storage and occasional, short-term exposure; for more than 1-2 weeks of continuous exposure, use the 365 Series.
-
365 Series Cover: An outer acrylic-coated woven polyester layer with an inner solar-material radiant barrier liner, designed for continuous 24/7, year-round outdoor protection, with a warranty that includes 24/7 exposure.
Will this Telegizmos cover help my telescope cool down faster?
Yes. The aluminized surface is a highly effective solar radiant barrier. By reflecting sunlight, it keeps the telescope's optical tube significantly cooler than if it were left uncovered, which reduces the time needed for the optics to acclimate to nighttime temperatures.
What is the Telegizmos cover material made of? Is it Mylar?
No, it is not Mylar. The material is a proprietary multi-layer polyethylene with a fully aluminized surface. Its embedded fibrous webbing makes it strong and tear and puncture resistant. It was originally developed for NASA as an insulator in spacecraft.
Can condensation still form under the Telegizmos cover?
Yes, under certain conditions, condensation can form on any covered object. In environments with high humidity or rapid temperature drops, moisture can still condense on the telescope's surfaces underneath the cover. It is always good practice to allow your equipment to air out when conditions permit.
